As of February 7 at 13:00 UTC, China's National Health and Health Commission had received a total of 31,261 confirmed cases of the 2019 Novel Coronavirus (2019-nCov) outbreak and 26,359 suspected cases, which was a leap of 4,833 from the day before. As of February 8 at 03:00 UTC the 2019-nCoV had killed 725 people, all but one of them in China. Like SARS, HIV, Ebola, and influenza, the 2019-nCoV is an RNA virus. Its single-strand structure makes it more susceptible to mutation and more difficult to develop vaccines for. In mid-January, Chinese scientists isolated the first 2019-nCoV strain and published its genetic sequence to aid in independent detection of the virus.
